Now-a-daysvideo sharing has become a very popular application in Online Social Networks (OSNs) like Facebook, Twitter, Google+, etc., but its sustainable development is impeded by the natural limitations of the Client/Server architecture applied in current OSN video systems. The three main limitations are 1) Expensive in terms of server bandwidth 2) Storage and 3) not scalable with the rapidly increasing number of users and video content. Recently many peer-assisted Video-on-Demand (VoD) techniques have been proposed, where peers who all are in online contributed their bandwidth in delivering the video content. But unfortunately, videos can only be shared through friends in OSNs. Therefore, present VoD works on two things 1) clustering nodes with similar interests 2) close location for high performance are optimal, if not entirely inapplicable, in OSNs. We propose a model called SocialBook for peer-assisted video sharing in online social networks system that addresses node failure problems associated with overlay construction using DHT (Distributed Hash Table) aided Chunk Driven Overlay which selects stable nodes, we also explore social relationship, social distance between video viewers and length of videos. We evaluate SocialBook through prototype experimental result and an event-driven simulator show that SocialBook can improve the quality and scalability.
